Application filed November 18, 1916. Serial No. 132,084.

To all 'whom t may concern:

Be it known that l, WARD S. lRELAND, a citizen of the United States of America, a resident of the city of St.- Louis, State of Missouri, have invented certain new and useful improvements in Type-Writing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, forming a part .of this specification. f

My invention relates to improvements in typewriting -machines', and more particularly to paper feeding mechanism adapted for use in shorthand machines. One of the objects of the invention is to produce a strong, simple and accurate paper feeding device adapted to coperate with the finger keys of a shorthand machine, and adapted to .advance the paper a fixed distance during each key operation. The paper feeding device moves a iixed distance during each operation, and since the paper is positively prevented from slipping by the positive gripping devices, it travels a fixed distance during each operation. An accurate papel` feeding device of this kind is particularly adapted for use in a shorthand machine wherein the paper is to be fed step by step (line by line) in response to the key operations.

With the foregoing and other objects in view the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown ythe preferred embodiment of the invention; however, itis to be understood that the inventioncomprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

Figure I is a longitudinal section of a shorthand machine embodying the features of my invention.

Fig. II is a vertical section taken approximately on line II-IL Fig. I.

Fig. III is a detail View showing the paperfeeding device in its normal or starting position.

Fig. IV is a view showing the parts as they appear at the end of the paper feeding operation.

Fig. V shows the parts in the positions they occupy during their backward, or return movement.

` to the line of bon toward the type and Fig. VH is a fragmentary view illustrating the roll of paper and the friction devices f associated therewith.

To illustrate the invention, l have shown a shorthand machine provided with a housing 1, a type holder 2 arranged in said housing (Fig. l), a type bar 3 loosely secured in said type holder, a yieldable abutment 3 arranged in the type type bar 3, and an inking ribbon 4 adjacent type on the type bar 3. The paper passes from a supply roll A, over a roller 5, under and partially around a roller 5', in front of and over an uncurling device 6 and then t0 the paper feedincr device whereby it is unwound from the rollJ and fed through an opening 7 at the rear of the machine. I

The key actuated devices preferably 1nclude a series of angular levers each having an upwardly extending arm 8 at its front end` (Fig. l) and a character key 9 at the upper end of said arm. Any suitable shorthand code may be used, and if desired, the keys may be provided with characters corresponding to the line of type characters on the type bar 3. Each key lever 1ncludes an arm lOextending rearwardly from its arm 8 and an arm l1 extending upwardly from the rear portion of said arm 10. The series of key levers is pivotally supported by a pivot member 12 located at the junctions of the lever arms 10 and 11. The upper end of each lever arm 11 is provided with a forwardly extending hammer 13 which lies adjacent to the type 3. Restoring springs 14 (Fig. connected to the lever arms 10, tend to retain the upper ends of lever arms 11 in engagement with an abutment 15.

When one of the linger keys 9 is depressed, the key lever associated therewith turns about the axis of pivot member 12 and a printing hammer moves toward the type 3, thereby forcing the paper and inking ribprinting one of the type characters on the paper. The key levers may be operated independently of each other, or any desired number of key levers may be operated simultaneously.

The universal bar associated with the key levers includes a transverse abutment 18 arholder and fitted to the ranged in front of the series of lever arms 11 and engaging all of said lever arms. rlhe universal bar also includes a pair of arms 20 and 21 pivotally supported by the pivot member 12 arranged on opposite sides of the lever arms 11, and secured near their upper ends to the transverse abutment 18. 23 designates a restoring spring (Fig. I) conneeted to the universal bar and. tending to retain it in the position shown in the drawings. The transverse abutment 18, forming part of the universal bar structure is so arranged that the universal bar will move in response to movements of any one of the key levers.

24 designates a key lever guide, arranged near the Junctions of the lever arms 10 and 11, andV adapted to receive the wings which extend rearwardly from the key levers and universal bar, as shown in Fig. I.

The paper feeding device preferably comprises a stationary supporting frame having a pair of sidemembers 25, secured at their lower ends to the key lever guide 24. A main pivot rod 26, extending across the stationary frame, is mounted in bearings at the upper ends of the side members 25. A. pair of carrier arms 27 pivotally supported by the main pivot rod 26, extend upwardly from said pivot rod and constitute a sup-` port for the gripping elements. Fach carrier arm 27 is preferably provided with an upper gripping link 28, a lower gripping link 29, and operating links 30 and 31 connecting said gripping links to an operating lever 32. Pivots 33 and 34 connect the gripping links to the carrier arms 27, the operating links 30 and 31 being connected t0 the upper ends of levers 32 by means of a pivot 35. lt will be noted that the gripping links 28 and 29 are connected to the operating links 30 and 31, so as to form a pair of toggles, and that the toggle structure may be operated to force the gripping links 28 and 29 toward and away from each other. The margins of the strip of paper A pass between the pairs of gripping links 28 and 29 as shown most clearly in Figs. II and IH. Pivot members 37 connect the toggle operating levers 32 to the carrier arms 27.

The driving device for transmitting energy from the universal bar to the toggle operating levers 32, comprises a sleeve 38 mounted on the main pivot rod 26, and having a pair of upwardly extending arms 39 to which the lower ends of the toggle operating levers 32 are pivoted, the upper end of each arm 39 being provided with a pin 40 which lies in a slot at the lower end of a lever 32. An arm 41, extending downwardly from the sleeve 38, is connected to the universal bar by means of a yieldable link 42. 43 designates restoring springs, connected to the carrier arms'27 and tending to retain the paper feeding elements in the positions shown in Figs. I and III.

To clearly understand the operation of the paper feeding device, it should ibe borne in mind that the gripping links 28 and 29, as well as the operating levers 32, are pivotally supported by the carrier arms 27, the latter lbeing supported by the main pivot 26. When the parts occupy their normal, or starting position, (Fig. III) Vthe restoring springs 43 tend to pull the carrier arms 27 forwardly. At this time the arms 39, extending upwardly from sleeve 38, are stationary and the restoring springs 43 tend to pull all of the gripping elements forwardly independently of said 7arms 39. Since the pivot members 37, yconnectin the levers 32 to the carrier arms27, are .pu led forwardly while the levers are engaged with the stationary pins 40, the springs 43 tend to turn said levers 32 about their axes, the result being that the upper ends of levers 32 are forced forwardly so as to force the gripping links into engagement with the paper when Y ln feeding the paper, the universal bar pulls the link 42 in the direction indicated by the arrow in Fig. III, thereby forcing the gripping elements into engagement with the paper, and at the same time feeding the paper. rl`he gripping action is due to the fact that the pivot pins 40, carried by arms 39, tend to turn the toggle operating levers 32 about the axes of their pivots 37 thereby forcing the grippinglinks toward each other and into engagement with the paper. The energy for driving the carrier arms 27, during the operation of feeding the paper, 1s transmitted from the universal bar, through link 42, arm 4,1', sleeve 38, arms 39, pivot pins 40, and then to the toggle operatmg levers 32. Thle toggle operating levers, therefore, serve\as means for transmitting energy to the gripping links to force them into engagement withthe paper, at the same time transmitting energy to the carrier lll@ arms 27, so as to advance the paper while it cated by the arrow in Fig. V, thereby turning the arms 41 and 39 about the axis of pivot 26. At the beginning of this return movement the pivot pins 40 at the upper ends of arms 39, are thrown very quickly from the position shown in Fig. IV to the position shown in Fig. V,.thus turning the Lara-iva toggle operating levers 32 on their pivots 37 to release the gripping links 28 and 29 from the paper. The means for restoring the universal bar is preferably designed to act quicker than the springs 4:3 which restore the carrier arms 27, the object being to retain the gripping links in their inoperative positions (Fig. V) While the springs 43 are pulling the carrier arms 27 to their starting positions. It is to be understood, however,

Athat the gripping links are inclined in such a manner that they Will not pull the paper very severely in returning to their starting position, even though the means for restoring the universal bar does not act more rapidly than the light springs 43 which restore the carrier arms 27.

The means for preventing retrograde movement of the paper comprises a paWl 50, pivoted to a stationary army 51, and engaging the paper, as shown most clearly in Fig. VI.

The inner end of the strip of paper is firmly secured toa core 55 (Figs. 1 and VH) provided at its ends with friction members 56 and 57 which turn with lthe roll of paper. A friction member 58, engaging the friction member 56, is rigidly secured to a stationary arm 59. 60 designates a yieldable friction member slidably fitted to a spring pocket at the lower end of a stationary .arm 61. A spring 62 forces the friction member 60 into engagement with4 the friction member 57, at the same time forcing the friction member 56 into engagement with the stationary friction member 58. The roll of paper is supported by pins, or trunnions 63 which extend from the friction members 58 and 60. The spring `pressed friction elements tend to prevent the roll of paper from turning, and upon the operation of the paper feeding device the paper is pulled along the uncurling device 6 (Fig. I), said uncurling device being a small rod located above the printing elements and fixed to stationary parts of the machine. In passing overl the uncurlin device 6, the strip of paper is turned a ruptly in a direction opposed to the direction in which it Was Wound on the roll. By holding the paper under tension and pulling it over the uncurling device in the manner illustrated, the paper is uncurled and fed from the machine 1n an absolutely uncurled condition. My paper feeding device is Well adaptedy to pull the paper against the resistance offered by the friction elements, for the paper is firmly gripped between the inclined links 28 and 29 and the resistance offered to 'the movement of the paper tends to pull the links backwardly with respect tov the movement of the paper, thus tending to grip the paper more firmly between the gripping faces of said links.
